IMPROVEMENT IN HINGES.

Specification forming part of Letters Patent No. 130,729, dated August20, 1872.

biningwith the ordinaryleaves of ahinge an extra leaf, which is attachedto the pintle, and intended to be screwed upon the side of the jamb orpost facing the edge of the door or gate when closed; the object beingto transfer a portion of the strain upon the neck connectin g the strapand knuckle of the Ieaffastened.

to such jamb or post to such extra leaf, lessening the liability ofrupture of the former at f the point mentioned.

Figure 1 is a perspective view of my improved hinge. Fig. 2 is a plan oredge view of the same. Fig. 3 is a perspective view of the additionalleaf detached.

The same letters of reference are employed in all the figures in thedesignation of identical parts.

I have illustrated my improvement in connection with astrap-hinge,theleaf A of which is intended to be screwed to the door jamb or gate-post,and the leaf B to the door or gate. The knuckle a of the leaf A isembraced by the knuckles b b of the leaf B in the usual manner, and anordinary pintle, O, passing through the knuckles, completes the joint.It is quite common in hinges of thiskind to become broken at the neckwhich connects the knuckle a to its leaf, by reason of the strain of thedoor or gate upon it to obviateor at tional leaf. An incidentaladvantage of the employment of this extra leaf consists in the factthat, it will prevent the screws or nails used in securing the leaf Afrom working loose.

I am aware that a third leaf is not of itself new, and such, of itself,I do not claim.

What I claim as my invention, and desire to secure by Letters Patent,is-- The leaves A and B, combined with the additional leaf D, whichlatter isto be secured to the post at right angles to the plane of thedoor when closed, the knuckles and the pintle both falling without theplane of the leaves A B when they are both in a rightline, this arrangement being such as to allow the door to move through half a circle,all as described.

In testimony whereofI have signed rnyname to this specification in thepresence of two subscribing witnesses.
